Specification of Letters Patent.

' Application filed December 29, 1818. .Serial No. 809,284.

To all whom it may concern:

"Be it known thatI, WILLIAM LAWN-- scnnAcnn, acitizen of the United States, residing at Cincinnati, in the county of Harm ilton and State of Ohio, haveinventcd certain new and useful Improvements in Stitching for Securing Shank Eye Buttons and Methods of Forming the Stitching of which the following is a: specification.

' My invention relates primarily to stitching for securing shank-eye buttonsto shoes and to the method ofhttaching such buttons to the shoe, and I-haveshown and described my invention with relation to such use from which its application to shank-eye buttons in other relations may be readily perceived.

It is one of the "objects of my invention to secure shank-eye buttons in place in a novel manner so that the eye of the button is affixed closely to the surface upon which the same is secured. It-is a further object of my invention to provides. novel stitching and method of forming the same whereby the stitching for each button independently secures the. button in place; further to provide a. novel. stitching and method of form ingthe same whereby each button is maintained inplace by a knotting in the stitching; further to provide a stitching and method of forming the same for securing the shank-eye button in place by means of asingle thread so manipulated as to pass a plurality of the stretchesrof eilocpof the thread through the shankgeye of the button and'through'thematerial at both sides of the? shanlceye; and,-further to secure the loop in placebelow the surface at which the 1 button is located.

I have shown and described one form of my improved stitching and method of forming the same in aseparate application exeouted by me of even date herewith, being Serial No. 809,283, filedDecember 29,1913,

and have broadly claimed my improved stitching and method of forming the same in said application. The stitching and method offorming the same her'ein shown and described and. claimed is an elaboration upon the stitching and method of forming the same shown and described in my other aforesaid application and differs in some particulars therefrom.

The stitching may be formed manually or.

ous stages in the course of the formation of.

the stitching'these stages being'selective or arbitrary stages selected at points in the formation of the stitching which will most clearly showthe manipulation of the thread, it being understood that, especially when the stitching is formed by machinery, the operations or manipulations preferably take place in continued and uninterrupted series of steps for forming the stitching.

The invention will be further readily understood from the following description and claims, and fromthe drawings, in which latter: 7

Fig. 15 is an enlarged perspective View of the completed stitching, showing the head of the button broken away and showing the material in dotted lines for better illustration of the stitching; and.

Fig. 16 is a plan View of the stitching, the heads of the buttons being broken away, shown in connection with the coiiperating shoe part having the button-hole therein.

While the stitching of my improved method may be accomplished either 7 by manual manipulation or by the operation of mechanical means, it will be assumed for convenience of description, that the stitching is being formed by suitablemechanism in which the material, shown at 11, is fed in the direction of the arrow (1; This material may be the quarter of a shoe. It will be further assumed that a preceding button or buttons have been attached to the material, and that the stretch 12 of the thread, the latter indicated generally'at 13, passes from the stitching of a preceding button to the position at which the stitching for the button being secured in place is located. It will be further understood that stitching,

I which I illustrate in the drawings, is formed by a single thread, which may have its source at a bobbin or spool.

At the point where the stitching to be formed is located, the thread is passed through a hole 14, suitably formed in' the material either concurrently with "bi" independently of the passing of the thread through the hole, depending on whether a thread-needle or a hook-needle isemployed for the purpose. The'thr ead is received through the hole for forming a primary loop 15, (see Fig. 1); i

The shank-eye 16 of the button 17 is located about t e primary loop, l see Fi gffi). This may be accomplished concurrently with the passage of' the primary 1001) the hole'i l'or after the primary loop has been receivedthrough the hole. .7 The shank-eye o-f tliybutton is ananged cibssaseuf the stitching, its rounding 18 being arranged to be received under the primary loop and to extend crosswise of the stitching so as tobe secured with its shank-eye in line with the button-hole 19 in the coacting flap 20 of the article. This coacting flap may represent the button-fly of the shoe. The rounding isthereby placed close to theouter face 21 of the material.

The primary lengthwise of the path of the stitching, (see Fig. 3), which path is indicated by the dotted line 22 in Fig. 12, and is received reversely through the material through a hole 23, (see Fig. 4), distanced from the hole 11 a distance corresponding to the length of the stitching, which is ordinarily from threesixteenths to a quarter of an inch when stitching shoe-buttons. The primary loop may be either pulled orpushed through the hole 23, depending on the instrument em.- ployed, if mechanical means or a tool is used for accomplishing the purpose.

By the means so far stated both stretches of the primaryloop are received through the material in reverse directionsat the respec tive sides of the shank-eye ot the button and the rounding of the buttoneye received un-. der both said stretches. The primary loop is for convenience described as comprising an initial stretch 24 and a supply stretch 25.

A secondary loop 26 extends: from the primary loop. For forming this secondary loop I prefer to lead a. portion of the supply loop 15 is then deflected stretch 27 of the thread through the primary 6 of said primary loop proximate to the sec- 0nd hole of the stitching. r .3

The secondary loop is flexed in reverse'di rection, as indicated at 31, (see'Fig. =6), and pulling strain preferably exerted upon the same for stretching the stretches of the primary loop and forming a knot 32*between the primaryloop and'the secondary loop, this knot being preferably-formed below the surface 21 of the material at the-bight 3310f the primary loopibetween the primaryloop and the initial stretch 34; of the secondary loop. The rounding 18 of the shank-eye of the button is thereby firmly :pressed against the surface 21 of the material. This reverse stretching of the secondarylo'op preferably locates this knot u'n*der the intermediate theliole 14 alongsid' the stretohes' of the thread theretofore passed through said hole, (see Fig. 10) as indicated at 39. 1

The needle having'been Withdrawn from said hole, if a needle is employed in the operation, a pulling is exerted upon the tertiary loop, whereby the bight of the secondary loop is drawn toward the brght of the primary loop and the secondary loop drawn taut, forming a knot 40 between the supply stretch 41' of the secondaryjloop and the thread of the primary loopjand' a further knot 42 formed between the initial stretch 43 of the tertiary loop and the thread of the secondary loop. The knots 32, 40' and 4:2 are located preferably adjoiningly, and preferably form a compound knot between the primary loop and the loop 38. The loops 15 and 38 are shown arranged in concatenated relation. (See Fig. 11.)

The bight portion of the tertiary loop is flexed lengthwise of the path of thestitching, as shown at 45, and the loop spread asshown at 46, (see Figs. 11 and 12), for'being received about the button and about the button-shank. Pulling is thereupon exerted upon the supply stretch 47 of the tetiary loop, preferably by pulling upon the supply stretch of the thread for drawing the tertiary loop tightly about the shank-eye of the button, which thereby forms a locking of the stitching (see Figs. 13, 14:, 15 and 16), and also preferably forms a knot 48 between the supply end of the supply stretch of the tertiary loop and the secondary loop, this stretching aiding further in tightening the previous knots formed in said stitching. The stretches of the tertiary loop preferably pass crossingly over the stretches of the firstnamed loop adjacent to the initial hole 14 for forming hitches 49, 50.

The pulling taut of the tertiary loop also has a tendency to force the shank of the button toward the hole from which the tertiary loop protrudes for wedging the rounding 18 of the shank under that end of the primary loop protruding from said hole and forcing said rounding toward the material. The supply stretch of the thread is then passed to the position for the formation of the next stitching for securing the next button in lace.

The bight 51 of the tertiary loop is received above both the initial stretch 24 and the supply stretch 25 of the primary loop, (see Figs. 13, 14, 15 and 16), the stretches of the tertiary loop being located preferably at the side of said streteheaofi the primary loop located above the outersurface of the material and'at the edges and slightly under the rounding'of the shank-eye of the button.

The eye shank ot the button is caused to lie close tothe outer face ofthe material to which itis 'attaehedgwithl'the shank arrangedatfig stitching and in line with the button-hole '19, shown in the coadting flap "20 of themate'rial, which in a shoe represents the buttonfly, the button in a shoe being attached to the mating edge of the opposite quarter.

Having thus 'fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The method oi -attaching a s hank-eye button to -material which consists in passing a l'oop of thread comprisin an initial stretch and a: supply stretch trough the material through-the shank-eye of the but ton" and reversely through them-aterial passing the supply limb of the thread through said loop for forming a supplemental loop, forming a locking loop concatenated with said supplemental loop, and passing said locking loop through the material and about the l shank-eye of the button.

I 2." The method at attachin ashank-eye button to nit ate-rial whiehaconsists in passing a primary loop of thread through the material, through the shank-eye of the button and f 'reyerse'ly 'tlirdu'g'lf the material, passing the supply-limb of the thread through said primary loop for forming a secondary loop, drawing said primary loop taut for forming a knot between said loops, passing the suppl -limb of said thread through said secon ary loop for forming a tertiary loop, and passing said tertiary loop through the material and about the shankeye of the button and drawing said tertiary loop taut.

3. The method of attaching a shank-eye button to material which consists in passing a primary loop of thread through the material, through the shank-eye of the button and reversely throu h the material, passing the supply-limb 0. said thread through said primary loop and drawing said primary loop taut for forming a knot between said loops, passing the supply-limb of said thread through said secondary loop as a tertiary loop, drawing said secondary loop taut for forming a compound knot between said primary and tertiary loops, passing said tertiary loop through the material and about the shank-eye of the button, and drawing said tertiary loop taut for forming a knot between said secondary and tertiary loops.

l. The method of attaching a shank-eye button to material which consists in passglesto thos-path of the ing a loop of thread comprising an initial stretch and a supply stretch through the material at the beginning portion of the stitching-and through the shank-eye of the but- =ton, and reversely at the end portion of the stitching, passing the supply stretch of said thread from the beginning portion of the stitchin through the bight portion of said loop an drawing said looptaut, forming a compound knot at said bight portion with a supplemental loop extending therefrom, passing said supplemental loop through the material to the face side thereof at the beginning portion 01: the stitchingand about the shankeye-of the button, and drawing said supplemental loop taut.

5. The method of stitching a shank-eye button to material which consists in passing aloop of thread comprising a pair of stretches through the material and through the shank-eye of the button and reversely through the material, passing one of the stretches of said thread through the bight portion of said loop and drawing said loop taut, forming a compound knot at said bight portion with a supplemental loop comprising a pair of stretches extending therefrom, passing said supplemental loop through the material to the face side thereof and about the shank-eye of the button, and drawing said supplemental loop taut with its stretches arranged crossingly' over: the stretches of said first-named loop.
